Phenolic Antioxidant

Phenolic antioxidants exhibit a weak absorption tail extending well above 300 nm which makes them easily transformed when they are irradiated with terrestrial sunlight wavelengths 80 As a result phenolic antioxidants are not very effective UV stabilizers However alkyl-substituted p-hydroxybenzoates (e g UVA-BZ-1) exhibit little if any absorption of terrestrial sunlight wavelengths
